A novel cis-trans photoisomerization of vinylidenecyclopropanes via excited singlet and triplet states
Photoisomerization of cis- and trans-1-diarylvinylidene-2,3-dimethylcyclopropanes is described. The formation of different photostationary state mixtures of cis and trans isomers generated by direct and triplet-sensitized photoreactions clearly shows that the photoisomerization proceeds via their excited singlet and triplet states, respectively.
